daab2e94da Convert xstrfmon() into a wide-character version xwcsfmon()
Also work around buggy implementations of strfmon() that do not copy
complete multibyte sequences that may be part of a locale's
mon_thousands_sep, thousands_sep, mon_decimal_point or decimal_point.

1e0285f6c0 Rename l_strfmon() and rewrite as xstrfmon() to handle POSIX locale better
Current and previous versions of ISO/IEC 9945-1 (POSIX), particularly SUSv3
(2001) and SUSv4 (2008), require strfmon() to return rather meaningless
strings when used with the POSIX "C" locale.  In particular, the standard
POSIX locale does not define a currency symbol, a monetary radix symbol
(decimal point) or a negative sign.  This means strfmon(..., "%n", -123.45)
is supposed to produce "12345" instead of something like "$-123.45"!

The new xstrfmon() overcomes these limitations by using snprintf() as
appropriate.

2032f6de8a Move redefinition of _XOPEN_SOURCE into its own Autoconf macro and header
This makes the main source code look a little cleaner, at the expense of
background magic happening in the configure-generated config.h.  But this
magic was already happening for _GNU_SOURCE, __EXTENSIONS__ and the like.

The only wrinkle is that newer versions of NcursesW cause ./configure to
include "-D_XOPEN_SOURCE=600" as part of the compilation command line--on
systems that support _XOPEN_SOURCE=700.  The AC_DEFINE/AC_DEFINE_UNQUOTED
macros automatically comment out any "#undef" lines in config.h, so the
file lib/xopen_source.h works around this limitation.  It is
automatically included by config.h.

d35abf787a Remove any mention of Minix from NEWS
The Minix C library does not seem to support Unicode well (for example,
wcwidth() returns -1 for UTF-8 byte sequences), the native curses library
is quite buggy, playing around with the Gnulib wcwidth module did not fix
issues with Unicode--it's all in the "too hard" basket!

1b0387441f Report the command line necessary to compile under Minix 3.4.0rc6
Note that although Star Traders compiles and installs successfully,
running the binary with a locale set to use non-ASCII strings currently
fails with "mkchstr: 'STRING': Illegal byte sequence" ("STRING" being the
translated string).

1f734e960b Replace spaces with tabs and vice versa
For Star Traders, all text files use spaces only (no tabs); for C source
code files, tabs are used, except in comments, where spaces only are used.

097c9b0e5b Avoid a Clang warning about a comparison that is always false
Rewrite a check that unscramble_table[] is of the right size as an
assertion, which prevents Clang from issuing a warning that the "result
of comparison of constant 256 with expression of type 'const unsigned
char' is always false".

Oh for the day that C11's _Static_assert can be used amongst all
compilers!  But perhaps Gnulib's assert-h module can be used instead...

265ed12de8 Update to an unreleased version of ax_cflags_warn_all.m4
This version of the AX_CFLAGS_WARN_ALL macro uses a far more robust
method of detecting compilers to select appropriate warning flags.  It
also uses the AX_PREPEND_FLAG macro instead of AX_APPEND_FLAG.

This version of ax_cflags_warn_all.m4 (and ax_prepend_flag.m4) has been
submitted upstream; see https://savannah.gnu.org/patch/?9673 for details.

eb0ed43ce2 Bug fix: char may be unsigned on some platforms
The function wctob() returns an int that can be -1; a conversion to
unsigned char will make that value 0xFF.  Although the "if" statement
still works in this case, we should be more diligent in our programming.

192b749018 Use a better check for Solaris (SunOS 5.x)
The __sun__ macro is not always defined by Oracle Solaris Studio, but
__sun is, as it is in GCC and Clang.  By itself, __sun__ also matches the
very obsolete SunOS 4.x BSD-based operating system, hence the need for
__SVR4 as well.

See https://web.archive.org/web/20180221212835/http://nadeausoftware.com/articles/2012/01/c_c_tip_how_use_compiler_predefined_macros_detect_operating_system

de6f113d12 Change parameters of apply_xor() from void * to char *
Arithmetic on void * pointers is undefined, according to Section 6.5.6
Paragraph 2, Section 6.2.5 Paragraph 1 and Section 6.2.5 Paragraph 19 of
the ISO/IEC 9899:1999 C99 standard: the void type is incomplete and thus
its size cannot be determined.

GCC allows pointer arithmetic on void * as an extension (and only warns
if "-Wpointer-arith" is given); the Oracle Developer Studio C compiler
issues a warning by default.

a47e8528dc Force redefinition of _XOPEN_SOURCE if required
Newer versions of libncurses/libncursesw "#define _XOPEN_SOURCE 600" in
their pkg-config file.  This change forces _XOPEN_SOURCE to be redefined
to 700 in that case.
